An astronaut on TV just said they're designed to be slim and do exactly what's needed in this case: emergency life support in case the capsule loses pressure. They're custom fit, they don't have a lot of doodads hanging off them, I'm guessing you wouldn't use them for a spacewalk, but for a launch they get the job done and don't take up a lot of room.
